PRINTING ATTACHMENT FOR ENVELOPE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 510,043, dated December 5, 1893,.

7 Application filed March 6, 1893 Serial No.464,851. (No model.)

.To an whom it may concern: Y

Be it known that I, HENRY L. N EWELL, of Dayton, county of Montgomery, State of Ohio, have invented a new and useful Improvement in Printing Attachments for Envelope-Machines, of which the following is a specification.

The invention to be herein specified and claimed, relates to improvements in that class of reciprocating envelope machines that are provided with mechanism for printing or em bossing the blank, while it is undergoing the process of being made into an envelope.

More particularly speaking, the invention is confined to improvements in printing devices to be actively associated,in an intermediary relation, with the gumming and folding mechanisms, and operated therewith, by the power conveyed to a common shaft.

The object in view, is to provide an improved construction by means of which, the blank is printed at a most convenient point and in a most efiective manner as it is being carried to the folding or creasing point.

As introductory to the specification, the character of the invention, will be more readily comprehended by a brief mention of the successive steps in the operation, that the well known parts of the machine are called upon to perform in connection with the function performed by the part comprising the improvement. envelopes are formed are supplied to the machine at a point, and in a manner that is well known to those familiar with the art of envelope making, gummed by the picker, and are carried rearwardly to the folding station by a carrier, mention of which will be only incidentally made in the specification, and it has not been deemed necessary to furnish more than a brief illustration of these parts, in the drawings.

In Figure 1 of the drawings, the relative positions of the gumming and folding stations are denoted, respectively by A and B.

The drawings herewith appended as supplemental to the specification, will be referred to, and the reference characters thereon,will be found to indicate corresponding parts throughout the several views.

Fig. 1. is a plan view of the table, with the type bed not shown. The standards of the platen bar are shown in section.

The blanks, from which the This view gives the relative location of the picker, printer and folder, the printer occupying a central position. Fig. 2. is a rear elevation partly in section"; Fig. 3. an elevation of the side upon which the throw off mechanism is located; Fig. 4. a detached, detail view of the type bed, and eccentric, in perspective; Fig. 5. a detached, detail view of the device for breaking the fall, or deadening the jar occasioned by the type bed coming in contact with the table. The shafts supporting this device are shown in section.

The main shaft is indicated byFig. 1, and is provided with suitable hearings in boxes located at the sides of the machine; .to this shaft is attached the driving wheel 2 by means of which the system of gearing employed, is rotated. Immediately in the rear of the driving shaft, a similar shaft 3 is located, and upon which a gear wheel 1 is placed, that is capable of meshing with the driving wheel'2, and also with an intermediate gear wheel 5, pivoted to bracket 6. A similar bracket 7 is situated directly opposite to bracket 6, which provides therewith bearings for shaft 8; upon this shaft, pinions 9, l and 11 are located; the former is designed to mesh with the intermediate gear pinions l0 and 11, mesh respectively with gear wheels 12 and 13, which are fnlcrumed on a reciprocating shaft 14; attached to gear wheels 12 and 13 in a crank like manner, are the arms 15 and 16; the upper ends of these arms are likewise attached to the guides 17 and 18 of the vertical reciprocating platen bar 20, upon which the platen 22 is adj ustably supported.

Returning to shaft indicated by 14, which is pivoted to the pinion shaft 8, by straps 23 and 24., one of which appears in dotted lines in Fig. 3, vertically extending arms 25 and 26, are pivotally attached at one end to this shaft, the other end of said arms being pivotally attached to shaft 27, having an eccentric portion 28, formed in the center thereof; the purpose of this eccentric will be explained in the description of the parts with which it is operated.

The table is indicated by 29, and the type bed 30, is provided with a way 31 secured to the under surface of said table, beneath an opening therein, which opening, together with the way 31, provides means for the type bed 30, to be vertically reciprocated therein, by action of shaft 27, which receives its motion from shaft 14, as before indicated.

The type is provided with inking rollers 32 and 33 which are subjected to a reciprocating motion by means of a vertical rack bar 34, secured to arm 16, and designed to mesh with the pinion 35. Fig. 1 shows this vertical bar in section. Near the opposite end of shaft 36, upon which pinion 35 is secured, are likewise secured gear wheels 39 adapted to mesh with the horizontal racks 37 and 38, to which the inking rollers are secured. Only one of these gear wheels, (39,) is shown in the drawings; brackets 40 and 41 furnish bearings for the shaft, 36, and also guides for the horizontal racks 37 and 38.

The inking rollers are provided with bearers 42 and 43, at one end, adapted to be rotated over the track 44, as the horizontal racks 37 and 38 carry said rollers back and forth over the inking disk 45, and the type bed.

Thus far my attention has been concentrated upon the constructive features of my improvement. The operation thereof will be explained by referring to the primary source of power 2. The motion imparted by this wheel, is transmitted to the platen 22 through the system of gearing hereinbefore described, and the arms 15 and 16. The rotation of the wheels 12 and 13, carries the arms 15 and 16 therewith, until the said arms, lower the platen to a horizontal plane coincident with the plane of the blank; at this juncture, the guides 17 and 18, of the platen bar have reached the limit of their downward travel, and are in abutment with the lower terminal of the ways, as shown at 46, Fig. 2; it will be noted that owing to the limited longitudinal extent of the ways in which the platen guides 17 and 18 move, the shaft 14, is compelled to change its axis of rotation, to a higher plane, as shown by the dotted lines of the wheel 12, in Fig. 3; this change in the axis of the shafts rotation is provided for by the straps 23 and 24 which give it a pivotal connection with the pinion shaft 8. The change in the axis of rotation from a lower to a higher plane, imparts to the arms 25 and 26 a motion corresponding to the distance between the two axes of the shaft 14, which in turn causes shaft 27 to rise, and therewith the type bed, to meet the platen; at this point, the printing operation is performed upon the blank carried thereto from the picker, by the hooks 47 and 48 on the reciprocating carrier 49; there are also on this carrier, hooks 50 and 51 which carry the blanks from the printer to the folding station, indicated by B. It will be understood that at the time the hooks 50 y and 51 are removinga blank from the printer,

from on an incline; the object of these stops is to give the blank an exact adj ustment after it has been carried to the printer; and to obviate any tendency the blank may have, to shift too far rearwardly by the momentum given it by the carrier.

I provide an automatic device for preventing the platen and type bed from impacting, should the carrier, for any reason, fail to carry a blank thereto. This consists of a thrust rod 53, bifurcated at its lower extremity so as to straddle the shaft 3; this rod is also, near its lower end, provided with an anti-friction roller 54, designed to normally rest upon the periphery of cam 55, and thereby furnish a bearin g for said rod; the bifurcated or forked portion of said rod serves to prevent it from moving laterally, and the ofiice of the spring 56 is to apply the necessary tension to the rod 53, and thereby maintain the roller 54 at all times in bearing with the cam 55. This cam is secured to shaft 3, in a rigid manner, and

it will be seen in Fig. 3, presents to roller 54, three degrees of peripheral contour, as it is rotated. The upper extremity of rod 53, has an elongated slot therein, to which an arm 57 is loosely connected by means of the stud 58 at one end. To the other end of this arm, the rocking rod 59 is fixed. 60 and 61 represent arms rigidly attached to this rocking rod. These arms are provided with downwardly projecting fingers 62 and 63 and stops 64 and 65; immediately beneath the fingers are apertures6666 and 6767 in the plate 68.

Referring again to the thrust rod 53, it will be understood that the stud 58, is allowed to move freely within the limits of the slot in the thrust rod, at times occupying a position at the upper or lower terminal of said slot. It will be understood, that in the event there is not a blank present on the printer when the fingers 62 and descend, they fall into the openings 66; the motion given to the rocking rod 59 at this moment is by force of gravity, and the weight on this rod is so counter-bah anced that the blank is sufficient to support it. The fingers while on their lowest plane of travel, bring the stud 58in thehighest portion of the slot, but said stud is not elfected by the movement of the thrust rod 53, until the intermediate surface of the cam 55 is presented to the roller 54, at which time the fingers are removed from the apertures. In the description of this mechanism it is in order to state'that 69 represents a downwardly projecting arm attached to the rod 59, to the lower end of which, is attached by a link connection, the angular lever 70, pivoted to the under surface of the table 29, shown in dotted lines in Fig. 1; at the other extremity of this lever a downwardly projecting block'7l, is secured.

On shaft 27, a dog 72 is rigidly secured and maintained. in a horizontal position by springs 7 3 which are secured to shaft 27. These springs apply tension to the said shaft and thereby give the dog 72, a normal tendency.

attached to the arm in this position of the dog, the highest portion of the eccentric 28, is in contact with the lower surface of the type bed 30.

When the hooks 47 and 48 on the carrier, are conveying a blank to the printer, to occupy the position shown in dotted lines in Fig. 1, the fingers 62 and 63. are in the position shown in Figs. 2 and 3, and the roller 54 on thrust rod is upon the highest peripheral surface of the cam 55; when the blank assumes the position shown in dotted lines in Fig. 1 the fingers 62 and 63 descend by gravity to rest upon it; the said roller, on the thrust rod, is at this juncture in contact with the lowest surface on the periphery of the cam, at this moment the imprint is made upon the blank; the continued rotation of the cam next brings theroller in contact with the intermediate surface of the cam; at this point the fingers 62 and 63 are elevated from the blank, but the stops 64 and 65 are permitted to remain on the plate 68, to prevent the blank imprinted from being carried forward by hooks and 51, which at this moment are passing under said blank to convey it to the folding station. The continued rotation of the cam brings the roller 54 again in contact with the highest peripheral surface of said cam; the thrust rod 53'rocks the fingers 62 and 63 and stops 64 and entirely away from the blank and permits it to be carried to the folding station B, and at which time the hooks 47 and 48 convey a blank to the printer. When the fingers are at their highest elevation, as appears in Figs. 2 and 3, the

block 71 is at its greatest distance from thedog 72, as appears in dotted lines in Fig. 1. When there is no blank upon which the fingers may rest, they drop by gravityinto openings in the plate, as hereinbefore mentioned in connection with the reference to the slotted thrust rod 53 and thereby brings the block 71 directly in the path of the dog 72, as said dog is brought upwardly by the arms 25 and 26, and the shaft 27 is thereby rocked to bring the eccentric portion 28 out of the position shown in Fig. 2, permitting the type bed to fall a sufiicient distance to avoid meeting the platen.

I provide means to be finally described,for breaking the fall and lessening the jar occasioned by the downward movement of the type bed against the table; represents a thrust piece pivoted to shaft 14 and provided with forks at its lower end adapted to straddle shaft 1. Upon this forked piece a roller 76 is placed and a cam 77 is rigidly attached adjacent thereto on the shaft 1 adapted to rotate therewith against the roller 76 and thereby meet said roller, as it is being Vertically lowered by the downward movement of shaft 14. These parts are shown in Figs. 2 and 5, with the point of the cam 77 at its lowest plane; the type bed at this time is also at rest upon the table; as the type bed ascends, the shaft 14, it has been noted, necessarily ascends therewith and the thrust or' forked piece 75 with the roller 76; in the mean time shaft 1 is rotating the 'cam 77, when the highest vertical plane is reached by the point on said cam, it presents a position directly the reverse to that shown in Fig. 5; the antifriction roller 76 is then bearing on that periphery of the cam, having the greatest incline, and gradually makes the circuit of said incline, until the cam again assumes the position in Fig. 3. Thus it will be noted, the fall of these parts is not attended with any considerable amount of opposing friction yet the parts are gradually allowed to fall their proper distance.
